Answer:
Discontinuity: x = -3 and x = 3
Zero: x = 0
Step-by-step explanation:
We know that a function is discontinuous, when the denominator of the function is 0. So let's see what the denominator equals.
x2 - 9 = 0
+9 = +9
x2 = 9
x = + 3
Now lets find the zeros of the function by substituting y = 0 in the function.
0 = 3x/(x2 - 9) (x2 - 9)
0 = 3x
0/3 = 3x/3
0 = x
This means that the function is discontinuous at points x = -3 and x = 3. the zero of the function x = 0.
Answer:
C
Step-by-step explanation:
assuming point (0,0) is D
let assume mid point of line DA is E
so x and y coordinate of point E
(x , y) = ( (4m+0)/2, (4n +0)/2 )
(x, y ) = ( 2m, 2n)
let assume F is the midpoint of line BC
so coordinates of point F is
(x , y) = ( (4q+4p)/2 , (4n+0)/2 )
(x , y ) = (2q+2p, 2n)
so now the coordinate or midpoint of mid segment EF is
(x , y) = ( (2m+2q+2p)/2, (2n+2n)/2 )
(x , y) = (m+q+p, 2n)
To solve this question, we first need to layout the equation
-2 1/2 -(-1 3/4)
Step 1
-2 1/2-(-1 3/4) ... Equation
Step 2
5/2-(-1 3/4) ... Converted to improper fraction
Step 3
5/2-(-7/4) ... converted to improper fraction
Step 4
5/2--7/4 ... Got rid of parenthesis
Step 5
-3/4 ... Subtract
Answer:
-3/4 ... Answer
So the answer for this problem is C, -3/4
